As I have above considered it expedient to place Ephemerum in 
Funariacee, on the same principle Acaulon and its allies (Phascacee, 
C. Muell., excluding Ph. crispum, multicapsulare, polycarpum and ros- 
tellutum, which belong to Weisiace@) must go into Pottiacee. The 
near affinity of Pottia minutula to Phascum cuspidatum, &c. is too 
obvious to require proof; and as there are some Phasca (e. g. Ph. 
bryoides) which have an easily separable, not to say deciduous lid, there 
_ would seem to be no character, either natural or artificial, sufficiently 
constant to justify the separation of the latter from Pottiacee.
